Just moved in my newly acquired 125g tank and after setting it on the stand noticed a place where the glass has been damaged. I have no idea when or how the damage occurred. It does not appear to completely compromise the glass, but it is at the point where the front bonds to the left side.
Would you guys look at the pics and give me opinions? Thanks very much- I SO hope my tank can be saved!

Is it just chips blown out from the corner? Its hard to tell from the pics. I've seen tanks with chips missing from the corners that were up and running for years with no issues. as long as the sealant is in good standings I expect you should be fine. Have you water tested the tank yet?

yup, it's just the corner and does not seem to have affected the seal on the inside at all. My gut feeling is that it's ok- I'll water test tomorrow. Do you think it best to fill the tank completely to get full pressure on the crack? That's what I'm thinking.

I had the same problem in my tank when I first got it. There was a small chip on one of my corner panes...I had it up for about a month, when I woke up one morning to find my tank half full. I had to pull up the carpet to dry it out..the sealant where the chip was located had sprung a leak. I ended up removing that entire pane, and resealing it.
